READ ALL THE STEPS BEFORE STARTING THE CONVERSION.
INSTALLER NOTICE: THESE INSTRUCTIONS MUST BE LEFT WITH
THE APPLIANCE.
This kit contains components required to convert this appliance
from using Propane Gas to using Natural Gas as the only fuel.
All of these components must be replaced in order for the unit to
operate safely on Natural Gas.
When installing gas components use pipe joint compound or
Teflon tape on all pipe fittings before installing (ensure propane
resistant compounds are used, do not use pipe joint compounds
on flare fittings).
INSTALLATION INSTRUCTIONS
TURN OFF THE GAS SUPPLY TO THE APPLIANCE.
Step 1. Using an 1/8” allen wrench, remove the control panel cover by
removing the 4 button screws around the control panel (indicated
by arrows in Figure 1). Do not disconnect any wires during this
step.
Remove regulator

Step 2. Remove the knob extensions on the gas control and flame height
knobs by pulling them off.
Step 3. Using a Torx T20 or flat screwdriver, remove the Nova SIT LP
Regulator (flame height knob) by removing the 3 screws sur-
rounding it (see Figures 2 and 3) . Be sure to also remove the
LP regulator diaphragm (see Figures 2 and 4).
Step 4. Install the Nova SIT NG Regulator (included in this kit) using the
3 new screws provided as shown in Figure 3.

Step 8. Move the air shutter off of the orifice. Using a 1/2” open end wrench,
remove the orifice by turning counterclockwise. See Figure 9.
Step 9.
Using a 1/2” end wrench, replace the LP orifice with the NG main
burner orifice included in this kit (#31 for 40,000 BTU or #36 for
33,000 BTU). See Figure 9.
Step 10.
Using a 7/16” open-end wrench, loosen the stem of pilot hood
assembly with a 1/4 turn counterclockwise (see Figure 10).

Step 16. Turn on gas supply and test for gas leaks using a gas leak test
solution (see Test Procedure on Page 18 of the Installation and
Operation Manual).
Step 17. Using a manometer, test the inlet and manifold gas pressure
per instructions in the Installation and Operation Manual (Page
18) and as shown in the following 2 tables.
Step 14. Reinstall the log set and glass door assembly. See Page 12
(Log Set Installation) and Page 25 (Door Assembly Installation)
in the Installation and Operation Manual.
Step 15. Light the appliance per the lighting instructions label on appliance
(located inside left door) or lighting instructions on Page 19 of
the Installation and Operation Manual. Inspect for proper pilot
and burner flame appearances (see Figures 15 and 16 below).

Step 15.Remove the sticker covering the model on the label so that it
reads “Epic NG40” if orifice #31 is installed. Use the sticker
“Epic NG33” to cover “Epic NG40” on the label if orifice #36
is installed. The label is located on the inside of the left hand
door (see Figure 14).

Step 14. Before you secure the burner with screws, double check that
the orifice is positioned into the burner neck by feeling around
the back of the burner (see Figure 13). Then, lower the burner
so it sits flush on the burner supports and replace the 2 screws
removed in step 6 (see Figure 13).
Reach behind burner and feel orifice to
ensure it is centered in the burner neck
